Three more weapons from Fast and Furious have turned up at crime scenes in Mexico, CBS News has learned, as the toll from the controversial federal operation grows.

According to Justice Department tracing documents obtained by CBS News, all three guns are WASR-10 762-caliber Romanian rifles. Two were purchased by Fast and Furious suspect Uriel Patino in May and July of 2010. Sean Steward, who was convicted on gun charges in July 2012, purchased a third. The rifles were traced yesterday to the Lone Wolf gun shop in Glendale, Ariz.

During Fast and Furious and similar operations, federal agents from the Bureau of Alcohol, Tobacco and Firearms (ATF) encouraged the Lone Wolf and other gun stores to sell massive amounts of weapons to questionable purchasers who allegedly trafficked them Mexican drug cartels.

Patino is said to have purchased 700 guns while under ATF’s watch. Ever since, a steady stream of the guns have been recovered at crime scenes in Mexico and the U.S. But the Justice Department has refused repeated requests from Congress and CBS News to provide a full accounting. An estimated 1,400 guns are still on the street or unaccounted for.

This will be going on for years. The body count from weapons sent to the cartels by Obama and Eric Holder’s DOJ and ATF will continue to go up.
